This Whole30 Shepherd's Pie is packed full of savory flavors like thyme and rosemary. Lamb meat is topped with fluffy, buttery mashed potatoes toasted to perfection under the broiler. Dairy free and gluten free. Use ground beef for a Whole30 Cottage Pie instead.
Add the chopped potatoes to a stock pot full of salted water and bring to a boil. The water should be about two inches over the top of the potatoes. Boil 20-30 minutes until the potatoes can be easily pierced with a fork.
